This note presents an alternative way to perform discretization of the <br>column-integrated continuity equation in pressure-type vertical <br>coordinate semi-Lagrangian models. The properties of this alternative <br>form have not yet been pointed out in the literature to the authors' <br>knowledge, and the aim of this paper is to briefly review some of its <br>potential advantages or disadvantages for NWP modeling, namely with <br>respect to behavior with mountains and to mass-conservation properties.</div>
